Counterfactual Data Augmentation with Contrastive Learning

no code implementations7 Nov 2023 Ahmed Aloui, Juncheng Dong, Cat P. Le, Vahid Tarokh

To address this, we introduce a model-agnostic data augmentation method that imputes the counterfactual outcomes for a selected subset of individuals.

Individual Treatment Effects in Extreme Regimes

no code implementations20 Jun 2023 Ahmed Aloui, Ali Hasan, Yuting Ng, Miroslav Pajic, Vahid Tarokh

Understanding individual treatment effects in extreme regimes is important for characterizing risks associated with different interventions.

Causal Mediation Analysis with Multi-dimensional and Indirectly Observed Mediators

no code implementations13 Jun 2023 Ziyang Jiang, Yiling Liu, Michael H. Klein, Ahmed Aloui, Yiman Ren, Keyu Li, Vahid Tarokh, David Carlson

This is important in many scientific applications to identify the underlying mechanisms of a treatment effect.

Mode-Aware Continual Learning for Conditional Generative Adversarial Networks

no code implementations19 May 2023 Cat P. Le, Juncheng Dong, Ahmed Aloui, Vahid Tarokh

To this end, we introduce a new continual learning approach for conditional generative adversarial networks by leveraging a mode-affinity score specifically designed for generative modeling.

Domain Adaptation via Rebalanced Sub-domain Alignment

no code implementations3 Feb 2023 Yiling Liu, Juncheng Dong, Ziyang Jiang, Ahmed Aloui, Keyu Li, Hunter Klein, Vahid Tarokh, David Carlson

To address this limitation, we propose a novel generalization bound that reweights source classification error by aligning source and target sub-domains.

Unsupervised Domain Adaptation

Transfer Learning for Individual Treatment Effect Estimation

no code implementations1 Oct 2022 Ahmed Aloui, Juncheng Dong, Cat P. Le, Vahid Tarokh

To this end, we theoretically assess the feasibility of transferring ITE knowledge and present a practical framework for efficient transfer.
